Ehm, a NullPointerException should be obvious...
if no property is selected resp. the last was
unselected, the
returned value will be NULL of course.
Hi,
I am developing a protege plugin and I want to get the
selected
object property from an
owlobjectPropertySelectorPanel, So I
introduced this line to check such requirement
JLabel lab=new
JLabel(objectPropPanel.getSelectedObject().asOWLObjectProperty().getIRI().getFragment());An
exception at this line was raised(captured from the
console or
log)
NullPointerException: null ..... (XYZ.java:81)
Could you please help me, was my use of
getSelectedObject is
incorrect?
Thank you in advance.
